SPECIFICATION forming part of Letters Patent No. 391,827, dated October30, 1888.

Application filed Nay 9, i838. Serial No. 273,290, (No modi-l.)

To all whom it may concern:

Be it known that I, HERRMANN TiMMEL, a citizen of Germany, residing atPotschappel, in the Kingdom of Saxony, German Empire, have inventedcertain new and useful Improvements in Door-Hinges; and I do declare thefollowing to be a full, clear, and exact description ofthe invention,such as will enable others skilled in the art to which it appertainstomake and use the same, reference being had to theaccompanying drawings,and to the letters and figures of reference marked thereon, which fornia part of this specification.

Figure I is a sectional side view of my iur proved hinge. Fig. 2 is aside view of the cap. Fig. 3 is a vertical central section of the same.Fig. 4 is a cross-section on linexw, Fig. l. Fig. 5 is a cross-sectionon line y y, Fig. 2; and Fig. 6, a cross section on line z e, Fig. 3.

This invention relates to a door-hinge so constructed that it embodieswithin it a lubricator, from which the lubricant may be admitted to theseveral joints of the hinge.

The invention consists in the various features of improvement more fullypointed out in the elaini.

.The letter A represents the pintle of the hinge having a rounded upperend. Upon this end rests the reduced end of a cap, A, free to turnthereon. To the cap A there is secured by a pin, s, the upper leaf, B,of the hinge. Through the cap A there extends from the top to bottom aperforation, a, having on top a flaring mouth, Z), which may be closedby a tightly-htting plug, c. The redueedlower end of cap A is slotted,as shown at d, and through this slot the lubricant that may have beenintroduced into perforation a is free to enter be tween the cap and theleaf B, and also between the cap and the upper end of pintle A as soonas the plug c is removed, so as to :admit airpressure.

In order to admit the lubricant between the pintle A and the leaf B, andalso between the two leaves B B, the tubular portion of the upper leafthat surrounds the pintle is provided with a pair of interiorlongitudinal grooves, e, Fig. 4. These grooves are, under ordinarycircumstances, out ofliuewith groove d, to exclude the lubricant fromthe grooves; but when it is desired to admit the lubricant the pin s iswithdrawn, and the leaf B is then turned until the grooves d registerwith the grooves c. The lubricant is now free to flow between pintle andleaf, and also downward between the two leaves. Vhen a sufficientquantity of the lubricant has been admitted, the door is swung back andthe pin s is reintroduced.

The combination of perforated cap A, hav ing slot cl, with theA pintle Aand with the leaves B B', the upper leaf having groove e, and with thepin s and plug c, substantially as specified.

In testimony7 whereof I affix my signature in presence of two witnesses.

HERRMANN TIMMEL.
